BACKGROUND

1. Field of the Invention

This invention relates to lightweight portable concealment and sheltersystems and methods.

2. Description of Prior Art

There is often a need to conceal oneself when researching wildlife,hunting, camping, working on construction projects, or working in theoutdoors. Wildlife researchers conceal themselves so that they can filmand study wildlife without disturbing the behavior of the animals.Hunters often conceal themselves in various hunting blinds to avoidbeing detected by their prey. Campers often conceal themselves to bathe,change clothes, and perform other personal or hygiene activities.Construction workers, military, law enforcement, and others who work inthe outdoors also have similar needs for concealment. Various methodshave been employed to accomplish these tasks.

In the past, quite complex, heavy structures have been built orconstructed for concealment. Hunters have built permanent huntingblinds. Portable huts, shower stalls, dressing shelters, tents,canopies, and complex tree blind structures have been carried into thegreat outdoors.

The related applications provided lists of patents and products relatingto this field of invention. The discussion of these prior art referencesis included by reference.

The use of such devices has several disadvantages such as being heavy,bulky, noisy, expensive, and complicated to assemble or use. Most ofthese devices have only a single use with poor performance. There is aneed for a simple, lightweight, compact, portable, multi-use means ofconcealment.

To avoid being detected by their scent, hunters and other wildlifeobservers climb trees using tree steps and then remain for hours in atree stand watching and waiting for animals to pass by. However, aperson in a tree stand makes a silhouette against the sky or backgroundand is exposed to a 360-degree view. Animals can easily detect the humansilhouette or movement. Further, if the person or equipment makes anoise the animal will know where to look. There is a need for a devicethat eliminates the silhouette.

Complicated equipment or procedures create a situation where a personmay drop equipment or, even worse, fall from the tree stand. Most of theexisting devices block the view or mobility of the person.

Metal objects screwed into trees are sometimes forgotten and become overgrown by the tree. Later when the lumber is harvested and cut, the sawstrikes the metal object and can cause severe damage. Some states havebanned the use of metal tree screws or spikes. Any device used forattaching to trees in the forest needs an embodiment that attaches tothe outside of the tree and can be easily removed.

The following ground blinds or tents are known in the art:

-   -   Hunter's Specialties' “Lightweight Portable Ground Blind”    -   Avery' “Avery Quick Carry Ground Blind”    -   U.S. Pat. No. 5,062,234, entitled “Portable Blind”    -   Double Bull “Matrix”    -   Cabela's “Lightning Set” and “Lightning Set 4-Season”    -   Black Stump's “Instant Tent”

There are a number of very old patents relating to curtain supportbrackets. These are associated with hanging curtains inside a buildingon a wall and fail to anticipate many novel features of the presentinvention.

There are also a number of very old patents relating to tents withhinged shafts, such as U.S. Pat. No. 1,502,898, Berg, filed Jan. 12,1924, or umbrella tents, such as U.S. Pat. No. 1,649,219, Goldberg,filed Mar. 23, 1927. U.S. Pat. No. 74,933, Palmer, issued Feb. 25, 1868,disclosed an inverse umbrella-type frame deployed by a rope external tothe enclosure. U.S. Pat. No. 3,794,054, Watts, issued Feb. 26, 1974,disclosed an inverse umbrella tent.

However, these are limited in various ways.

Human Body Strength and Skin Tighting

In the field of lightweight, portable outdoor blinds, there is a longfelt need to have skins extremely tight to avoid detectable movement andnoise. Numerous blind designs have attempted to provide the desired skintightness but have failed without using complex, heavy frames thatrequire significant time and athleticism to set up. Those that arelightweight and fast, such as conventional umbrella designs, fail to putenough force into the frame to provide the desired result. Further,because many blind products have promised, but have failed to deliver,cover skins that remain substantially motionless in windy conditionsencountered while hunting, consumers are skeptical. To be successful aproduct must also stay taut when shaken by potential buyers on the tradeshow floor or in dealers' show rooms.

The arm muscles (biceps and triceps) of the human body are relativelyweak compared to other muscle groups such as the legs, abdomen, back,and shoulders. This is especially true when arms are extended away fromthe body above the shoulders as is required to deploy conventionalumbrella type blinds. Such blinds are set up with the frame expanded inan upright position and the operator either a) pushing up from insidewith one hand while pulling a pull cord or shaft down with the otherhand, or b) pushing down from outside with one hand while pulling a pullcord up with the other hand while standing beside the structure. Forexample, see the art cited in U.S. Pat. No. 6,354,316, Chen. Neither ofthese conventional methods take advantage of the strongest musclesgroups in the body to provide the skin tightening force.

In the power jerk position, the full human body can apply hundreds ofpounds of force between the hands and the feet. In 1970 for example,Olympic lifters were able to clean and jerk over 500 lbs. A typicaloutdoorsman can apply up to about 75 pounds of continual force in thepower jerk position. A six-foot human body has about 33 inches up toabout 40 inches of range of motion in the power jerk.

In a horizontal, seated row position, for example as used in Olympicrowing, all of the large muscle groups of the body, including legs,abdomen, back, shoulder, and arms, are used to apply the force throughthe body between the feet and the hands. A typical outdoorsman can applyup to about 75 pounds of force in the seated row position, with anaverage of about 40 pounds over the full stroke. A six-foot human bodyhas up to about 45 inches of range of motion in the seated row position(and about up to 65 inches if the arms are extended beyond the head).

Work or energy is measured in foot-pounds. When an operator applies anaverage of 45 pounds of force over a distance of 3.5 feet (i.e. 42inches) about 157 foot-pounds of energy is applied. About the sameamount of energy could also be stored by applying 57 pounds of forceover a distance of 2.75 feet (i.e. 33 inches).

What is needed is a method of setting up a blind where the full musclestrength of the human body from hands to feet can be used to quicklyprovide the skin tightening force to a lightweight, portable blind.

Although arch shaped quickset blinds have been used with some success,the arch shape does not provide maximum headroom close to the walls, anda larger amount of energy must be stored in the arches to achieve skintightness.

What is needed is a structure where headroom is maximized near the wallsof a blind or tent and where skin tightening forces are provided byrelatively small mechanical movement.

People spending time in the outdoors, especially warfighters, often havea need to quickly set up shelter for them and their equipment.

What is needed is a tent that can be quickly deployed to provideprotection from rain, snow, heat, and insects and reptiles.

DESCRIPTION OF THE INVENTION

The present invention comprises an easy to use, simple, lightweight,compact, portable modular system for concealment and shelter and methodsfor its construction and use. The main components of a basic module arevarious novel supports and a curtain. The support attaches to astructure and pivots at the attachment. Other modules include novelcovers with cover shafts, a removable floor, a rain fly, and variousnovel flies and shields. The modules can be combined to form varioustree blinds, ground blinds, waterfowl blinds, blinds attached to vesselsor vehicles, and various shelters. The system uses novel shaft segmentsthat can be attached in various configurations and then broken downwithout detaching the attachments. The present invention encompassesvarious embodiments of the attaching pivoting support as well as variousembodiments of curtains with various features. A method of the presentinvention allows for 360-degree concealment. In addition to a method ofbeing fully enclosed, a method of the present invention is based on theconcept of “hiding in front” of a similar pattern.

The present invention is also directed to various structures and methodsfor skin tightening for a shelter or blind, especially hunting blinds.Novel frame structures are used to stretch and thereby tighten the skinof a hunting blind. The present invention includes the discovery thatwhen a cover is stretched over an arched dome, the lower portion of eachcover wall is relatively loose. Various solutions to this problem areprovided. Various prior attempts to provide lightweight portable blindswith cover skins that remain tight in blustery, hunting conditions havefailed because the structure is too weak and/or the set up method doesnot allow a human operator to apply a sufficient force to the skintightening mechanism. The present invention includes novel structuresand methods that allow the large muscle groups of the full human body toapply a skin stretching force to set up a blind with previouslyunrealized results.

FIG. 1A through FIG. 1C

FIG. 1A illustrates an exemplary embodiment of an attaching pivotingsupport 100. The support 100 is bent at an angle. The bend 140 resultsin two legs: a first leg 150 and a second leg 160. The first leg 150 hasa threaded portion for threaded attachment to an attaching structure 130(FIG. 1B), such as a tree, pole, rock, wall, or attaching fastener 230(not shown—see parent applications). The bend 140 allows a user to exerta force on the second leg 160 that acts as a lever to screw the firstleg 150 into the attaching structure 130.

The angle of the bend 140 is shown as a 90-degree angle; however, goodresults have also been obtained by using an obtuse angle. An obtuseangle still provides a leveraged force but is less likely to cause thesecond leg 160 to be blocked by tree branches or other obstructions.

The attaching pivoting support 100 can be constructed of a single shaft.However, depending on construction materials, a lighter embodiment canbe constructed by combining various components. This inventionanticipates that any combination of parts can be used to make theattaching pivoting support 100 with equivalent structural features andfunctions. The embodiment shown in FIG. 1A is merely on example of thosedisclosed in the parent applications.

FIG. 1A shows a currently preferred embodiment the attaching pivotingsupport 100 comprised of the sleeved support 3102 and the second leg 160comprised of a plurality of channeled shaft segments 3199. Additionaldetails and alternatives of construction and advantages regarding FIG.1A are provided in the POLE1 application included herein by reference.

FIG. 1B

FIG. 1B shows an operator 400 concealed by a support 100 and a curtain300. The operator 400 may be washing or taking care of other personalhygiene.

The means of concealment quickly and quietly can be lowered as shown byan angular path 410. This allows the operator 400 to look over thecurtain 300 or to shoot an arrow or fire a gun behind them without beingobstructed by the means of concealment. After firing, the user canquickly and quietly return the curtain 300 to its normal position asshown.

The curtain may contain one more slits (not shown) through which theoperator may look or shoot.

One objective and advantage of the present invention is maintaining thefrictional force of the first leg 150 with the attaching structure 130.This frictional force holds the attaching pivoting support 100 in placewhen not being moved by the operator 400. The operator 400 can alsoangularly raise the support 100 so that the operator's head is alsoconcealed by curtain 300.

FIG. 1C

FIG. 1C shows the use of three stakes (e.g. stake with cord clips andleg 3456) and two curtains 300 to form a ground blind. In this example,the stakes (3456) are inserted into the ground. Each stake (3456) isconnected to a shaft 106 (not visible). Curtains 300 a and 300 b aresupported by the shafts 106. The stakes 3456 can be placed in a line toform a wall, or diagonally to form a V-shaped blind.

Three or more curtains 300 could be used to form a fully enclosed groundblind.

FIG. 1D

FIG. 1D illustrates a pair of pivoting arches 3700. The pair of pivotingarches 3700 comprises an embodiment of pivoting intersection connector3500 (or 3500 b) and a plurality of full-length channeled shaft segments3199 or half-length shaft segments 3197. In one embodiment, the pair ofpivoting arches 3700 comprises three full-length channeled shaftsegments 3199 and one half-length shaft segment 3197 on each side ofeach arch (as shown).

FIG. 2A and FIG. 2B

FIG. 2A and FIG. 2B show the low profile blind with cover with quietwindows.

FIG. 2A shows a quiet cover 1646 that embodies a novel three-tieredcover. The top tier comprises a cover cap 1631. The middle tiercomprises a ring of windows 1612 that are held open or closed with novelmagnetic connections. The bottom tier is a skirt 2010 (which isproportionally smaller than the skirt 2010 disclosed for example in FIG.17 and in the related applications, i.e. the MOC3 application).

The magnetic connections, between magnets 4700 and magnetic pieces 4701,are a novel means for maintaining tight cover skin on the walls of ablind, while allowing quiet operation of the windows. In this regardmagnets are preferred over zippers 1633 and hook and loop fasteners 530(shown in the related applications). Each window 1612 has a magneticpiece 4701 attached to the lower edge of the window 1612, or sewn in thehem.

FIG. 2A shows the windows being held closed and taut using the magneticconnection between the lower magnet 4700 b and the magnetic piece 4701in the edge of the corresponding window 1612.

FIG. 2B shows the left front window 1612 a being held open using themagnetic connection between the upper magnet 4700 a and the magneticpiece 4701. The right front window 1612 d is held partially closed byits respective magnetic connection. The operator 400 is also shownpositioned within smaller, lightweight, portable, quick popup, quietcover 1646 embodiment. All of the components are attached together (forexample via cover loops 1622—not shown) so there are no parts to lose.This embodiment is simpler, smaller, lighter, and lower cost than theother full size, fuller function blind embodiments.

FIG. 3A through FIG. 3C

As discussed above, there is a need for embodiments of blinds and tentsthat can be set up rapidly and standalone in a variety ofconfigurations. FIG. 3A through FIG. 3C show various aspects andconfigurations of an embodiment of a fast setup frame 1534.

FIG. 3A shows a novel fast setup frame 1534. The fast setup frame 1534comprises a cover shaft intersection 1511 comprising a novelintersection dock 1722, an arch flattening means comprising a noveldocking assembly 1742, and a pull cord 1536 for operating the archflattening means.

A plurality of hinged cover shafts 1512 attach by hinges to the covershaft intersection 1511, so that each hinged cover shaft 1512 comprisehalf an arch. Thus, the hinged cover shafts 1512 are also referred to ashalf arch cover shafts 1512. FIG. 3A shows embodiments with four halfarch cover shafts identified as 1512 a through 1512 d. Similar fastsetup frames 1534 could be comprised of three or more half arch covershafts (see, for example, FIG. 11C showing three shafts)

This embodiment of the arch flattening means comprising a dockingassembly 1742 and a plurality of arch flattening shafts 1514(a-d) eachconnected to the respective half arch cover shafts 1512(a-d) with arespective, novel arch flattening hinge 1516(a-d). Each arch flatteningshaft 1514(a-d) is also connected to the docking assembly 1742, in thisembodiment, with a hinge.

The pull cord 1536 preferably is attached at one end to a pull handle1535.

The free ends of the half arch cover shafts 1512 each have an end piecemeans for attaching the fast setup frame 1534 to a cover 1540 (notshown). The end piece means are shown as end pieces with hook 4400(a-d),respectively.

FIG. 3B shows that, when the arch flattening means, shown comprising thenovel docking assembly 1742, is pulled toward and engaged with the covershaft intersection 1511, shown comprising the novel intersection dock1722, using the pull cord 1536, the arch is flattened. This archflattening results on a outward and upward skin tightening force beingapplied through the half arch cover shafts 1512 along the cover corners,as presented by the force arrows. With the novel features and methods ofthe present invention as described below, the human operator is able toapply a stronger skin tightening force over a longer working distancethan is possible with convention means and methods.

FIG. 3C shows an embodiment of the fast setup frame 1534 with four halfarch cover shafts identified as 1512 a through 1512 d. This embodimentshows another embodiment of the safety means comprising a safety strap1705 having receiving clip 1704 and an inserting clip 1706. When fullydocked, the operator applies the safety strap.

FIG. 4A through FIG. 4E

FIG. 4A shows various novel details of embodiments of the novel dockingassembly 1742, the novel intersection dock 1722, the novel archflattening hinge 1516, and a novel pull handle 1535.

The novel docking assembly 1742 comprises a docking plate 1746 and adocking shaft 1743 integrally attached to the docking plate 1746. Thedocking shaft 1743 has a rounded docking tip 1744 and an optional safetygroove 1745. In this novel embodiment the docking plate 1746 ispreferably about 3 to 4 inches or more in diameter and is sufficientlythick enough to provide substantial wall mechanical force against thesides of the respective arch flattening shafts 1514(a-d). In thisembodiment, the pull cord 1536 passes through the center of the dockingassembly.

The novel intersection dock 1722 comprises a novel dock plate 1724 and adock 1723 integrally attached to the dock plate 1724. The dock plate1724 features a plate hole 1769 extended to form a dock conduit 1727.The dock 1723 is shown with a novel outward curved surface 1725 forengaging the docking tip 1744 of the docking shaft 1743 when it is outof alignment. The dock curved surface 1725 gradually flattens to guidethe docking shaft 1743 into the dock conduit 1727. In this novelembodiment dock plate 1724 is preferably about 4 inches or more indiameter and is sufficiently thick enough to provide substantial wallmechanical force against the sides of half arch cover shafts 1512(a-d).In this embodiment, the pull cord 1536 passes through the center of thedock 1723 and dock conduit 1727.

The dock conduit 1727 is at least partially threaded on the exterior ofits extension so that it can receive a washer nut 1728. The washer nut1728 is used to hold the cover 1540 (not shown) material out of the dockconduit 1727 so material does not interfere with the operation of thedocking shaft 1743 (see FIG. 20A). Optionally, the washer nut 1728 alsoholds an embodiment of a foot attaching means 1790, such as foot plate1792 with gripping texture 1794 as shown.

The arch flattening hinge 1516 is integrally part of the hinged covershaft 1512(a-d) and has hinge walls 1518(a-b). The arch flattening shaft1514 is connected to the arch flattening hinge 1516.

The novel pull handle 1535 retains the pull cord 1536, preventing thepull cord 1536 from passing through the intersection dock 1722 andproviding tension when the operator 400 (not shown) wants to assert aforce through the pull cord. The pull handle 1535 preferably comprisesintegral hand grips 1776 for operator comfort and more secure grasp. Thepull handle 1535 also preferably comprises a handle standoff 1539 whichholds the handle in a known position that is easy to grasp while settingup the blind using the novel method shown for example in FIG. 6A, or thesequence from 14A to 14H, in particular at the transition from FIG. 14Dto FIG. 14E.

The pull handle 1535 also preferably comprises a handle snap receiver1538 that allows the pull handle 1535 to be temporarily locked onto acorresponding handle snap 1537 on the dock conduit 1727. The handle snap1537 and a handle snap receiver 1538 could be molded as a groove andring as shown; however, the handle snap means preferably is manufacturedas a groove in each part with an O-ring providing the snap. The handlesnap means is advantageous to avoid damage or injury or to provide asecure starting point when pulling the pull cord 1536 from the other endas shown, for example, in FIG. 15A and FIG. 15C.

As exemplary shown in FIG. 4A and FIG. 4B, the dock conduit 1727 is onlypartially threaded allowing the handle standoff 1539 to fit over thedock conduit 1727 above the washer nut 1728, and allowing room for thehandle snap 1537 (or other embodiment of the handle snap means).

FIG. 4B is a cross sectional view of the intersection dock 1722 and thedocking assembly 1742 having the same referenced items as FIG. 4A. Itfurther shows the position of an optional hand grip 1776 and hand guard1778 that would be used with an alternate embodiment as discussed inreference to FIG. 15A and FIG. 15C. The hand guard 1778 is of sufficientshape to engage the dock plate 1724 or half arch cover shaft 1512 beforethe operator's hand or fingers would be squeezed between the approachingparts.

As shown in FIG. 4A and FIG. 4B, the half arch cover shafts 1512(a-d)hinge on the dock plate 1724 and the arch flattening shafts 1514(a-d)hinge on the docking plate 1746. Like the arch flattening hinge1516(a-d), the hinge positions in the pates (1724 and 1746) are thickenough to form flat walls on either side of the shaft ends 1513(a-d).The optional safety groove 1745 shown, for example, in FIG. 4A and FIG.4B provides an embodiment of a safety means in combination with a safetyclip 1715 (FIG. 4C).

FIG. 4C shows a preferred embodiment of the safety clip 1715 which maybe attached to the blind with safety clip cord 1714. This embodiment ismade from a flat piece of metal or plastic with a central hole thatprovides a safety clip edge 1716 which mates securely with the safetygroove 1745 (FIG. 4B). When fully docked, the operator applies thesafety clip 1715. The safety means prevents the unplanned release of theenergy stored in the fast setup frame 1534. The safety means is removedbefore collapsing the blind (e.g. before FIG. 14H).

FIG. 4D shows a round wire clip 1717 embodiment of the safety clip 1715(FIG. 4C) made with round spring wire as is commonly known.

FIG. 4E shows a rectangular wire clip 1718 embodiment of the safety clip1715 made with rectangular spring wire, which has a more securely matingsafety clip edge 1716, than the round wire clip 1717.

However the embodiment of a safety clip 1715 shown in FIG. 4C iscurrently preferred because it a larger flat surface area making it morevisible to the operator and easier to grasp. Further, this embodimentcould be colored orange or red such that the operator would be lesslikely to forget to apply the safety means. An alternative safety means,namely a safety strap 1705 is discussed below in relation to FIG. 12Dthrough FIG. 12F.

FIG. 5A and FIG. 5B

FIG. 5A shows a covered blind 1540 (1621 or 1631) with vertical guylinemodules (1910, as previously disclosed in the related applications, e.g.the MOC3 application). The panels 1920 and 1922 can slide past eachother because each is attached on each side by a different guyline 1912(FIG. 5B). The operator can position the panels to cover the opening1602 as shown on the right (with blackout panel 1920) or with a portionof the opening 1602 covered by one panel (e.g. the blackout panel 1920on the left) and with another portion covered by the other panel (e.g.the see-through panel 1922 on the left). Note that the panels can slidebehind the cover 1540 (or 942) above or the curtain 300 (or skirt 2010,not shown) below because of the novel features of the modular systems.Horizontally guylines were previous disclosed as well.

FIG. 5B shows embodiments of guylines 1912 attached to the walls of thecover skin 1540. Guylines in the walls help maintain the wall tensionthat helps keep the walls taut and reduce motion or noise that may bedetectable by wildlife. FIG. 5B illustrates two exemplary openings 1602a and 1602 b, respectively in a cover 1540. A blackout panel 1920 aslides vertically up and down over opening 1602 a along guylines 1912 aand 1912 b and is held tightly in place by the novel use of a row ofmagnets 4700 at the edge of the opening 1602 a. When in this closedposition the wall tension is maintained through the blackout panel 1920a via the magnetic connection with the magnets 4700 as well as by theguylines 1912 a and 1912 b. A blackout panel 1920 b also slidesvertically up and down over opening 1602 b along guylines 1912 c and1912 d and is exemplary shown in the open position, revealing thesee-through panel 1922 (or shoot-through panel 1642) which likewise isheld tightly in place by the novel use of a row of magnets 4700 at theedge of the opening 1602 b. A row of magnetic pieces 4701 is attachedto, or in the hem of, the sliding panels (1920 or 1922) or the fixedshoot-through panel 1642. In the example on the right (i.e. over opening1602 b) the wall tension is always maintained via the magneticconnection with the row of magnets 4700 and corresponding rows ofmagnetic pieces 4701 as well as by the guylines 1912 c and 1912 d.Maintaining tension on the shoot-through panel 1642 also reduces theinterference with the flight of an arrow, for example.

The magnetic connections, between magnets 4700 and magnetic pieces 4701,provide a novel method of maintaining tight cover skin on the walls of ablind, while allowing quiet operation of the windows. In this regardmagnets are preferred over zippers 1633 and hook and loop fasteners 530(shown in the related applications).

FIG. 5C through FIG. 5D

FIG. 5C and FIG. 5D show operation of covers with guylines and windows.

FIG. 5C shows a quiet cover 1646 that embodies a novel three-tieredcover. The top tier comprises a cover cap 1631. The middle tiercomprises a ring of windows 1612 that are optionally held open or closedwith novel magnetic connections between magnets 4700 and magnetic pieces4701 (not shown—discussed above). The bottom tier is a skirt 2010.

The cover cap 1631 is connected to the skirt 2010 along the corners withskirt strap 1686(a-d). This is illustrated with skirt straps 1686 a and1686 d.

This embodiment also shows the novel use vertical guylines 1912. In thisembodiment the window 1612 material is sandwiched and held up betweentwo sections of guylines 1912. A plurality of guylines are shown acrossthe middle of each cover panel wall. Like the skirt strap 1686 in thecorners, the guylines 1912 connect the material of the cover cap 1631 tothe material skirt 2010, and thus help to maintain the skin tighteningwall tension, even when one or more of the windows 1612 are open. Theguylines 1912 also sandwich the material of the windows 1612 so that itdoes not flutter in the wind.

The bottom corners of the middle tier windows 1612 of the quiet cover1646 are shown preferably, removably clipped to the skirt 2010 withclips, identified in each respective corner as receiving clips 1704(a-d)and inserting clips 1706(a-d). These clips help maintain the walltension which keeps the blind cover skin taut.

FIG. 5D shows the embodiment of FIG. 5C with each of the visible windowspulled down and each of the corner clips connected.

Alternatively, the windows 1612 or panels (1910 or 1920, such as in FIG.5A and FIG. 5B) can be attached to straps with adjustable buckles thathold the window or panel material in place.

FIG. 5E

FIG. 5E shows an embodiment of the cover 1540 having a star window witha door 1634. Five window fasteners comprise a star-like layout 1590 witheach window fastener being one of the five parts of the star. A topwindow fastener 1210 extends upward from the center. The star windowlayout 1590 comprises multiple sections between the fasteners, includinga triangle section 1220, with a left section 1230 a and a right section1230 b on either side. A simpler window 1612 is also shown.

FIG. 6A and FIG. 6B

FIG. 6A and FIG. 6B show parts of a novel set up method of the fastsetup frame 1534. This sequence is shown using the alternate spreadingstrap means comprising two spreading straps 2160(a-b). The currentlypreferred wishbone strap 2162 (not shown here) could also be usedsubstantially as described below.

As disclosed in more detail in the parent application, the operator 400carries the blind using the spreading strap means, shown as the twospreading straps 2160, over a shoulder. Next the operator 400 places thecollapsed blind on the ground.

The operator aligns his body along the axis of the blind and placing hisfeet against the apex of the blind preferably using a foot attachingmeans 1790. The operator applies an initial spreading force by liftingand spreading the spreading strap means until the blind begins to open.The operator 400 leans back as the fast setup frame 1534 begins to open.FIG. 6A shows the operator 400 holding the spreading strap means withone hand (either with both spreading straps 2160 in one hand, orpreferably, with the one hand sliding down the wishbone strap 2162 (notshown) along the long strap). While the operator 400 continues to leanback, the other hand makes a smooth transition to the pull handle 1535.By leaning back, the blind continues to open and the operator 400 liftsthe apex of the blind off the ground using the foot attaching means1790.

FIG. 6B shows the operator 400 at the end of the seated row stroke. Thepull cord 1536 has been moved the full range of motion necessary toengage the docking mechanism of the arch flattening means. The operatorhas released the spreading strap means (e.g. 2160, shown hanging free).The operator has grasped the pull handle 1535 during the stroke withboth hands while continuing to lift the apex of the blind with the footattaching means 1790. Using this method the operator has been able toapply a cover skin tightening force using a plurality of large musclegroups of the full body from the hands to the feet, whereby the blind israpidly set up (in only a few seconds). The arch flattening means storesand transfers the force to the arch cover shafts 1512 (not shown). Inturn, the arch cover shafts 1512 stretch the cover panels 1542 (notshown) with sufficient force that cover skin is held taut withoutsubstantial movement or noise detectable by wildlife. The force appliedby the human body over the range of movement is greater than a forcepossible with just the arms and shoulders of the conventional methods.

It is during this transition from FIG. 21D to FIG. 21E that the secondadvantage of the flat walls in the various hinges is used. Thistransition puts a large stress on the frame as it tightens the skin. Themechanical stability provided by the tight hinges help align the dockingmechanism.

FIG. 7A through FIG. 7D

FIG. 7A through FIG. 7D show various features of an embodiment of a fastsetup frame 1534 (FIG. 3B) shown exemplarily with the quiet cover 1646and a novel self locking assembly 727 as a safety means.

FIG. 7A shows the collapsed fast setup frame 1534 where the pull handle1535 is necessarily close to the top of the blind. However when the fastsetup frame 1534 is deployed the pull handle 1535 is used to pull thedocking tip 1744 through the self locking assembly 727 via the pull cord1536 (FIG. 7B). The self locking assembly 727 comprises a safety pin 715which is spring loaded inside the horizontal housing (see magnifiedportion in FIG. 7D). The safety pin 715 is a safety means with similarfunction to those shown in FIG. 4C through FIG. 4E. When the safetygroove 1745 slides through the dock conduit 1727 the safety pin 715automatically engages the safety groove 1745 and locks the docking shaft1743 in place, until the operator 400 (shown in FIG. 7S) comes outsidethe fast setup frame 1534 to pull the safety pin 715 prior to collapsingthe frame. Thus, the safety pin 715 retains the docking shaft 1743 toprevent unplanned passage back through dock conduit 1727, which wouldresult in an unplanned release of energy in the fast setup frame 1534.

The advantages of the self locking assembly 727 are that the operator400 does not risk forgetting to attach the safety means and that theoperator must physically be outside the blind (i.e. away from thepossible head injury hazard) when the frame is collapsed (similar to theposition shown in FIG. 14H).

FIG. 8A and FIG. 8B

FIG. 8A shows a quiet cover 1646 that embodies a novel three-tieredcover (previously shown with fewer features in the embodiment of FIG.2A). The top tier comprises a cover cap 1631. The middle tier comprisesa ring of windows 1612. The bottom tier is a skirt 2010.

The cover cap 1631 is connected to the skirt 2010 along the corners withcorner sections 686(a-d). Similar to the structure shown in FIG. 5B, thecorner sections provide for taut skin.

This embodiment also shows the novel use vertical guylines 1912. UnlikeFIG. 5A and FIG. 5B, where the sliding panels 1920 or 1922 are attachedto the guylines 1912, in this embodiment the window 1612 material issandwiched and held up between two sections of guylines 1912. Aplurality of guylines are shown across the middle of each cover panelwall. Like the corner section 686 in the corners, the guylines 1912connect the material of the cover cap 1631 to the material of skirt2010, and thus help to maintain the skin tightening wall tension, evenwhen one or more of the windows 1612 are open. The guylines 1912 alsosandwich the material of the windows 1612 so that it does not flutter inthe wind.

FIG. 8B shows the embodiment of FIG. 8A with each of the visible windowspulled down.

FIG. 8C shows the embodiment of FIG. 8A further showing see-throughpanels 1922, similar to the see through panels 1992 shown and explainedwith reference to FIG. 2A and FIG. 5A.

Improved Designs

Although the enclosed blinds and tents with frames comprising archesshown earlier have had good results there are some problems with thesestructures. While the arch is high in the middle, as the user movestoward the walls, there is reduced headroom. In many situations, theuser does not want their head in the middle, rather they want their headcloser to the walls. For example a pair of hunters will sit near theback wall in respective corners so that they each have room to movetheir equipment (e.g. rifle, bow, or camera) and to avoid directsunlight reflecting off their faces. If more than one person is in ablind or tent they both can't be in the middle. For example, twowarfighters will want to be able to stand up, kneel, or sit on theirrespective sides of a tent, rather than moving to the middle to get moreheadroom.

While the arch structure previously disclosed for tightening skin on ablind has had great success, there is concern about the amount of energystored in the structure and force the would be exerted by the lower hubshould the energy be unexpectedly be released while a person was inside.FIGS. 9A through 16D relate to improvements over our previousembodiments, including embodiments with an angular frame which provideimproved headroom and reduce the range of motion required to release theskin tightening stored energy.

FIG. 9A through FIG. 9E

FIG. 9A illustrates an embodiment of a fully deployed and erectedangular frame 950 covered by an angular cover 942. In this embodiment asshown, the collapsible, quick popup angular frame results in a structurethat has improved headroom near the walls of the blind or tent.

The advantage of the angular frame 950 over the fast setup frame 1534 isthat fiberglass rods bent under tension over time eventually breakespecially if heated and cooled by changes in sunlight and outsidetemperature. The novel angular frame 950 does not require the fiberglassto be under as much tension therefore prolonging the life of the frame.

FIG. 9B through FIG. 9E show various aspects of the operation of anangular frame 950 used by the angular shelter shown in FIG. 9A.

FIG. 9B show a novel angular frame 950 comprising angular cover shafts952(a-d) and lower shafts 953(a-d) connected together by angular hinges956(a-d). A novel upper plate 945 connects the angular cover shafts952(a-d). Exemplary details of the upper plate 945 and lower plate 946interconnections are detailed for various embodiments explained inreference to FIG. 12A, FIGS. 16B and 16D. Each angular cover shaft952(a-d) is shown connected to respective stretcher shafts 954(a-d) atshaft plates 958(a-d) (see FIGS. 12G, 12H and 12I for exemplarydetails). Stretcher shafts 954(a-d) also connect to a novel lower plate946.

FIG. 9C illustrates that the angular frame can be folded to about halfthe length of the angular cover shafts 952 to collapse into a narrowbundle. When deployed the plates (945 and 946) are brought together,opening the angular frame 950. The angular hinge 956 allows theconnecting lower shaft 953 to rotate from parallel to a predeterminedangle.

FIG. 9D illustrates the lower shafts 953 rotated downward to a thepredetermined angle. FIG. 9D also illustrates a novel method ofdeploying the angular frame 950 using the full body strength of theoperator 400. A pull cord 1536 preferably is attached at one end to apull handle 1535. In this method the pull cord 1536 is pulled throughthe lower plate 946 and attached to a foot attaching means 1790. Theoperator 400 presses up on the lower plate 946 while using the largemuscles of the back and legs through a foot to apply a skin tighteningforce. The force of the body is transferred via the pull cord 1536 tothe upper plate 945.

FIG. 9E illustrates a fully deployed and erected angular frame 950.

In FIG. 9B through 9E the angular cover 942 was not shown so that theoperation of the angular frame 950 could be illustrated.

FIG. 10A through FIG. 10C

FIG. 10A illustrates the angular frame 950 in an upright position justbefore the plates (945 and 1946) are engaged. The angular cover 942 isloose over the angular frame 950. FIG. 10B illustrates a fully deployedangular frame 950. A small mechanical movement within the novel angularframe results in a significant outward and upward skin tightening forcebeing applied throughout the angular cover 942 by the lower shafts 953when deflected into the position as illustrated in FIG. 10C.

In contrast to the arched, fast setup frame 1534 (as shown in FIG. 3B)where the skin tightening force (as shown in FIG. 6B) is supplied by thebow of the half arch cover shafts 1512, the angular frame 950 provides asignificant outward force on the lower shafts 953 by a mechanicalrotation actuated by a relatively small shift in relative position ofthe lower plate 946 toward the upper plate 945.

FIG. 11A through FIG. 11E

FIG. 11A shows a low profile embodiment of the angular frame 950 designfor a single operator 400. The shafts 952 and 953 are both designed tobe preferably about two feet long. This allows the collapsed blind toeasily be carried on a backpack or waist pack. When deployed the blindprovides about three feet of useful headroom. This allows a singleoperator to sit comfortable within the concealment and protection fromsun, rain, snow, and wind provided by the blind. Note that for thesingle operator version the angle of the angular hinge 956 is moreobtuse than for a more typical larger structure, e.g. as shown in FIG.10C. The separation shaft 943 is longer in length to facilitate theshape of this single operator frame than would be needed for largerstructures with flatter roofs, for example, such as shown in FIG. 10C.

FIG. 11B shows an embodiment of an angular cover 942 having overheadwindow 1632 and cover window 1612 with guylines 1912.

FIG. 11C shows an embodiment of the angular frame 950 comprising athree-legged angular frame 1140. Corresponding parts have beenpreviously described. The shape of the plates and the location of theplate anchors 948 are modified accordingly.

FIG. 11D shows an embodiment of the angular frame 950 of FIG. 11C withthree cornered angular cover 1142.

FIG. 11E shows a single operator angular frame 950 configured for use ona hillside. The uphill lower shaft(s) 953 are folded up at angular hinge956, and the angular cover 942 is rolled up on the uphill side.

FIG. 12A through FIG. 12F

FIG. 12A is a cross sectional view of an improved docking mechanism.Stretcher shafts 954(a-d) respectively connect to plate anchors 948(a-d)on a novel lower plate 946. The separation shaft 943 is connected to thelower plate 946. Angular cover shafts 952(a-d) connect to plate anchors948(a-d) respectively on a novel upper plate 945. The upper handle 1262is threaded by the handle strap 1264. The handle strap 1264, which issuspened below the upper plate 945, is attached to the top of the upperplate 945 by two fasteners 1269. The threaded upper handle 1262, afterfastening, is allowed to dangle beneath the upper plate 945. The lowerhandle 1266 is attached to the lower plate 946 by a rigid handle bracket1268. This handle bracket 1268 is attached to the bottom of the lowerplate 946 by two fasteners 1269. The dashed lines shown for handle strap1264 are at an angle to the cross-section as more clearly shown in FIG.12D.

By pushing up on lower handle 1266 while simultaneously pulling down onthe upper handle 1262, the separation shaft top 944 is guided throughthe plate conduit 927 on the upper plate 945 and the separation shaft943 is inserted up to the separation shaft stop 947.

FIG. 12B illustrates a novel method of deploying the angular frame 950using only the upper body strength of the operator 400. The operator 400pushes up on lower handle 1266 while simultaneously pulling down on theupper handle 1262 to apply a skin tightening force to the angular frame950. This requires the use of upper body strength only and provides asignificant advantage of deployment of the angular frame 950 over thearched frame which requires the use of the full body including the legs(FIG. 6B and FIG. 9D).

FIG. 12C shows a single operator profile embodiment of the angular frame950 design for a single operator 400. The operator 400 uses the lowerhandle 1266 and upper handle 1262 to apply a skin tightening force tothe angular cover 942 of the angular frame 950.

FIG. 12D through FIG. 12F show perspective views of embodiments ofalternate improved docking mechanisms.

FIG. 12D is a perspective view of FIG. 12A with added safety straps 1705and clips comprising inserting clip 1706 and receiving clip 1704.Mounting the safety strap 1705 on the handle strap 1264 keeps thereceiving clip 1704 out of the area between the plate conduit 927 andseparation shaft tip 944 where it may otherwise be damaged.

FIG. 12E is a perspective view of an alternate embodiment of FIG. 12Dwhich uses pull rod 1263 instead of upper handle 1262. Mounting as shortsafety strap 1705 on the upper and lower plates 945 and 946 also keepsthe receiving clip 1704 out of the area between the plate conduit 927and separation shaft tip 944 where it may otherwise be damaged.

FIG. 12F is a perspective view of an alternate embodiment of FIG. 12Dwhich uses hand grip 1776 and hand guard 1778 instead of upper handle1262.

FIG. 12G through FIG. 12I

FIG. 12G through 12I show details of the shaft plate 958 connection tothe stretcher shaft 954. The end of stretcher shaft 954 that interfaceswith the shaft plate 958 is preferably flat and tight on either side ofthe shaft plate 958, such that the stretcher shaft 954 applies anadvantageous mechanical force against the shaft plate 958. The stretchershaft 954 could be composed out of solid, machined or molded, metal or afiberglass shaft with a metal tip.

FIG. 12G shows the position of the shaft plate 958 and the stretchershaft 954 when the frame is fully collapsed, FIG. 12H shows the positionof the shaft plate 958 and the stretcher shaft 954 when the frame isbeing set up. FIG. 12I shows the position of the shaft plate 958 and thestretcher shaft 954 when the frame is fully set up.

When the blind is initially being spread the shaft plate 958 connectionprovides an advantageous lateral force to cause the angular frame 950 tostart to open. The tightness and mechanical area of the connection isespecially helpful when the frame is in the horizontal position asrequired by the method shown in FIG. 14C through FIG. 14E. It alsoincreases the durability of the frame.

The shaft plate 958 and the stretcher shaft 954 connection provides asecond advantageous force to the angular frame 950, at point where theseparation shaft tip 944 enters the plate conduit 927, to help ensureproper alignment. Further, when the frame is fully set up, it continuesto provide stabilizing forces and strength within the angular frame 950to limit motion and breakage.

FIG. 13A through FIG. 13D

FIG. 13A shows a currently preferred embodiment of the blind in a lowprofile, rifle hunting configuration. The blind is low to the groundwith the extensions 4410 removed or folded inside the angular cover 942(not visible). The middle tier windows 1612 are closed because they areclose to the ground. For situations where it is desired to stay low tothe ground and shoot towards the sky, the operator 400 can lie insidethe angular frame and rise up through the overhead opening of the topwindow fastener 1210 when desired.

FIG. 13B shows a currently preferred embodiment of the blind in a doveblind configuration. On two of the four corners, the extensions 4410 areremoved or folded inside the angular cover 942 (not visible) moving theapex of the blind away from directly overhead. The middle tier windows1612 are closed. The operator 400 can sit on a chair inside the blindhaving good visibility through the opening and stand up wheneverdesired.

FIG. 13C shows a currently preferred embodiment of the blind in awaterfowl configuration. On two of the four corners, the extensions 4410removed or folded inside the angular cover 942 (not visible) moving theapex of the blind away from directly overhead. The middle tier windows1612 are closed. The two, interconnect inverted-T windows are completelyopened allowing the top to be completely open and rolled down.

FIG. 13D shows a currently preferred embodiment of the blind in ahillside or rough terrain configuration. On two of the four corners, theextensions 4410 are removed or folded inside the angular cover 942 (notvisible) allowing the blind to be level. The middle tier cover windows1612 are opened in part and are held quietly in place by the guylines1912. One side section of the inverted-T windows is shown open (byopening fasteners 1210 and 1212 a) allowing the operator to view up thehill.

FIG. 14A through FIG. 14H

FIG. 14A through FIG. 14G show novel set up and take down methods of theangular frame 950. This sequence is shown using the angular frame as acollapsed bundle having the angular cover shafts 952 unfolded to fulllength.

FIG. 14A shows the operator 400 carrying the collapsed blind using hishands. Next the operator 400 places the collapsed blind on the ground.At this point the angular frame 950 is folded to about half the lengthof the angular cover shafts 952 to collapse into a narrow bundle.

FIG. 14B and FIG. 14C show the operator opening the angular frame bygrasping the end piece with hook 4400 or the connecting lower shaft 953and rotating the shaft upward, outward and downward on the angular hinge956 (not shown) parallel with the angular cover shaft 942 and theground.

FIG. 14D shows the operator beginning to lean back while holding theangular cover shafts 952 through the angular cover 942 as the angularframe 950 begins to open. It is during this transition from FIG. 14C toFIG. 14D that the first advantages of the flat walls in the varioushinges are used. This transition puts a large stress on the frame toforce it to open. The friction within the hinges and against the groundstarts to hold the blind open. In practice, opening the blind into alight wind makes this step and process easier.

FIG. 14E shows the operator 400 at the end of the seated row stroke.While the operator 400 continues to lean back, the other hand makes asmooth transition to the pull handle 1535. By leaning back, the blindcontinues to open and the operator 400 lifts the apex of the blind offthe ground using the foot attaching means 1790. The pull cord 1536 hasbeen moved the full range of motion necessary to engage the dockingmechanism. The operator has released the angular frame 950 and hasgrasped the pull handle 1535 during the stroke with both hands whilecontinuing to lift the apex of the blind with the foot attaching means1790. Using this method the operator has been able to apply a cover skintightening force using a plurality of large muscle groups of the fullbody from the hands to the feet, whereby the blind is rapidly set up (inonly a few seconds). In turn, the angular cover 942 stretches over theangular frame with sufficient force that angular cover 942 is held tautwithout substantial movement or noise detectable by wildlife. The forceapplied by the human body over the range of movement is greater than aforce possible with just the arms and shoulders of the conventionalmethods.

FIG. 14F shows the operator 400 easily lifting the standalone blind andlifting it overhead.

FIG. 14G shows the operator 400 inside the blind. The operator can gofrom running through the outdoors to being fully concealed (the sequencefrom FIG. 14A to FIG. 14G) in about seven seconds.

FIG. 14H shows the novel take down method. “You just kick it.”™

The operator 400 pulls most of the pull cord 1536 inside the blind, andtips the blind horizontally to slightly below knee level. The operator400, for example, stands on a dominate right foot, holds the angularcover 942 with the left hand, and kicks the separation shaft tip 944with the left foot. When the stored energy is released, the blind willautomatically jump forward under the left arm of the operator 400 wherethe now collapsed blind also can be grasped in front of the body withthe right hand. The operator 400 can immediately move the blind to a newlocation. The blind can be collapsed in a couple of seconds.

For long-term transportation, the angular frame can be folded to abouthalf the length of the angular cover shafts 952 to collapse into anarrow bundle.

FIG. 15A through FIG. 15C

FIG. 15A through 15C show aspects and operation of an alternate powerjerk method of using the full human body to set up an angular frame 950.

FIG. 15A shows the operator 400 positioned under the angular frame 950in the power jerk position. The blind is initially spread while in avertical position. FIG. 15A also illustrates a novel method of deployingthe angular frame 950 using the full body strength of the operator 400.A pull cord 1536 preferably is attached at one end to a pull handle1535. In this method the pull cord 1536 is pulled through the lowerplate 946 and attached to a foot attaching means 1790. The operator 400presses up on the hand grips 1776 (configured as shown in one of theembodiments of FIG. 15B or FIG. 15C) while using the large muscles ofthe back and legs through a foot to apply a skin tightening force. Toachieve the full range of motion, the operator 400 likely will lift theblind from the ground as some point during the power jerk. The handgrips 1776 provide a stable means of performing the power jerk andautomatically positions the operator's hands away from the parts (e.g.stretcher shafts 954(a-d), half arch cover shaft 1512(a-d), upper plate945, or lower plate 946) that come together during the docking process.The hand guards 1778 (see FIG. 15B for details) help the operator tohold the collapsed frame when initially opening the angular frame 950and to protect the hands and fingers.

In yet another embodiment (not shown), the pull cord 1536 does not passthru the separation shaft 943, but is attached directly to the upperplate 945. In this embodiment there is not need for a pull handle 1535.

FIG. 15B shows a perspective view of the hand grips 1776 and hand guards1778 as an integral part of the lower plate 946. The stretcher shafts954(a-d) are connected to the lower plate 946 via the anchor plates948(a-d) respectively. The separation shaft 943 is attachedperpendicular to the lower plate and provides a conduit for the pullcord 1536. The pull cord extension 1533 is attached to the pull cord1536 by a closable clip 1937, in this embodiment.

FIG. 15C shows the hand grips 1776 and hand guards 1778 mounted on twoopposite arch stretcher shafts 954. FIG. 15C also shows the footattaching means 1790 attached to the pull cord extension 1533. The pullcord extension 1533 is attached to the pull cord 1536 by a closable clip1937, in this embodiment. The separation shaft 943 is attachedperpendicular to the lower plate and provides a conduit for the pullcord 1536. The foot attaching means 1790 could be implemented as a loopin the pull cord extension 1533 optionally attached or threaded througha stirrup 1799. The stirrup 1799 could be made of rigid metal orplastic, or preferably flexible plastic tubing.

Power Jerk Method

In the power jerk method of setting up the blind, the operator does nothave to sit on the ground (or chair) and still is able to use the largemuscle groups of the human body from hands to feet. While the range istypically less than the power row position, most outdoorsmen can applymore force in the power jerk position, resulting in the same amount ofenergy for necessary improved skin tightening, which is substantiallygreater than can be applied with just the arms and shoulders as inconventional methods.

FIG. 16A through FIG. 16D

FIG. 16A is a perspective view of an improved docking mechanism. Thedocking assembly 1742 comprising stretcher shafts 954(a-d) connected toplate anchors 948(a-d) by threaded axels 1763(a-d) respectively on anovel docking plate 1746. The docking shaft 1743 is connected to thedocking plate 1746. The intersection dock 1722 comprises angular covershafts 952(a-d) or half arch cover shafts 1512(a-d) connected to plateanchors 948(a-d) respectively on a novel dock plate 1724. The topportion of the dock plate 1724 in the intersection dock 1722 also servesas the foot attaching means 1790. The alternate dock 1721 is connectedto the bottom of the dock plate 1724. The inside of the alternate dock1721 comprises the dock curved surface 1725. The pull cord 1536 runscompletely through the docking plate 1746, the docking shaft 1743, thealternate dock 1721 and the dock conduit 1727.

By pushing the docking assembly 1742 into the intersection dock 1722,the docking shaft 1743 is guided through the bottom of the alternatedock 1721 and docking conduit 1727 and inserted up to the point wherethe bottom of the alternate dock 1721 meets the top of the docking plate1746 and the bottom plane of the safety groove is protruding above thetop of the docking conduit 1727. At this point a locking mechanism canbe applied to secure the docking shaft 1743 in place.

FIG. 16B is a perspective view of an improved dockless mechanism enabledby the mechanical strength resulting from the novel shaft plate 958 andnovel plate anchor 948. FIG. 16B eliminates the use of docking shaft1743, safety groove 1745, docking tip 1744, alternate dock 1721, anddock conduit 1727 and replaces it with separation shaft 943, separationshaft stop 947, separation shaft tip 944 and plate conduit 927.

The embodiment of the dockless mechanism in FIG. 16B is equally aseffective as that of FIG. 16A, but requires less material and the use ofan additional safety mechanism.

Other Uses

While the descriptions of the various embodiments have been made inreference to an undeveloped outdoor area, the modular system of thepresent invention could also be used in urban areas. For example, incolder winter climates, the system could be used to form a green houseover a garden using clear plastic sheeting and then reassembled in thesummer as a shelter for vehicles or bicycles using an opaque tarp. Inanother example, the supports, shafts, connectors, and curtains could beused to form a backyard maze. In yet another example, the system couldbe used for constructing outdoor structures for weddings, flea markets,festivals, or even security checkpoints.

Advantages Modular

The system of the present invention is modular. A user can begin usingsmaller modules with minimal investment and add more pieces or morecomplex modules later. A group of users can each own separate modules,which are used independently, and then construct more complexconfigurations when the group comes together in the outdoors.

Separately Packable

Because the various components and modules can be separated, differentusers in a group can carry a relatively lighter load, for example, intheir backpacks. Some modules such as the single operator angular blindis easily carried using a backpack or waist pack.

Star Window and Inverted-T Window

The novel star window configurations provide blind windows with four ormore sections such that any section or groups of sections can beindependently opened while maintaining taut cover panels. The starwindows, and inverted-T windows, also allow the top of the blind to befully opened. A novel window section attachment allows non-adjacentwindow sections to be attached.

Skin Tightening

The novel means of tightening the skin of the present invention providesmethods and means for tightening the skin on the sides of a blind coverto reduce movement and flutter in the wind. The means of the presentinvention include cover shafts that are stretched to cause a constantoutward pressure on the sides of the cover. This is done with lowercost, lighter weight, and easier to use structures.

Simple

The present invention is simple to make and use. Each component iseasily made. The present invention requires little time to attach and toset up.

The fast setup frame, angular frame, and other basic modules can bequickly set up to provide initial concealment and shelter. Othercomponents can be added and configured as needed.

Easy to Use

The present invention is easy to use.

Lightweight

The present invention comprises a few simple parts that can easily beconstructed of lightweight materials. Being lightweight is important forthose who have to carry gear into the outdoors.

Compact

The embodiments of the present invention are compact. Large modules suchas covers with cover shafts can be broken down and rolled together inrelatively small bundles. This is advantageous for both storage andcarrying.

Portable

The present invention is lightweight and compact allowing it to becarried long distances into the outdoors and to be used in a variety oflocations.

Quiet

The skin tightening features reduce noise from wind movement or flutter.The attaching pivot support with a curtain has no moving parts thatwould make a noise or rattle together. In some cases the screws turningagainst the attaching structure could make a quiet sound. However thedesign is such that once screwed in all the way the screw can be backedout a turn or two to reduce the volume of noise made to a negligiblelevel.

The novel use of guylines to secure and move windows and the use ofmagnetic window fasteners eliminate the need for zippers or hook andloop fasteners providing for quiet window or opening operation duringwildlife observation.

Universal

The modular system of the present invention uses the same brackets andshafts to construct a variety of both tree blinds and ground blinds. Thesame parts and equipment can be used to construct configurations fordifferent purposes and for different environments. This maximizes theuser's investment in the materials and minimizes the number of items tobe packed. The use of standard shaft segments and half-length extensionshafts provide for a large number of configurations using the same basiccomponents.

Lower Cost, Longer Reliability
